MODULAR CARRIER TOOL AND TOOL HEAD

摘要

The modular carrier tool (2), in particular drilling tool, extends along a central longitudinal axis (4) in axial direction (6) and comprises a carrier (8) as well as a tool head (10) that can be reversibly mounted on the front-end of the carrier (8). The carrier (8) has a head retainer (14) for the insertion of the tool head (10) as well as clamping webs (24), which radially delimit the head retainer (14) and also have bearing surfaces (28). The tool head (10) comprises clamping surfaces (35) extending in axial direction as well as underhead bearing surfaces (34). In a mounted state the clamping webs (24) clamp the tool head (10) in radial direction to the clamping surfaces (35) and the underhead bearing surfaces (34) are pressed against the bearing surfaces (28). In order to generate a force component (K) acting in radial direction unto the clamping webs (24), the bearing surfaces (28) as well as the underhead bearing surfaces (34) are tilted in radial direction towards the central longitudinal axis (4) by a tilt angle α. This particularly supports the radially exerted clamping force of the elastic clamping webs (24).

1. A modular carrier tool (2) which extends along a central longitudinal axis (4) in axial direction (6) and comprises a carrier (8) as well as a tool head (10) that can be reversibly mounted on the front-end of the carrier (8), wherein
the carrier (8) has a head retainer (14) for the insertion of the tool head (10) as well as clamping webs (24), which radially delimit the head retainer (14) and also have bearing surfaces (28) extending in a radial direction. the tool head (10) has clamping surfaces (35) extending in an axial direction as well as underhead bearing surfaces (34) in a mounted state the clamping webs (24) clamp the tool head (10) in radial direction to the clamping surfaces (35) and the underhead bearing surfaces (34) are pressed against the bearing surfaces (28),
characterized in that,the bearing surfaces (28), as well as the underhead bearing surfaces (34) are tilted by a tilt angle (α) in a radial direction relative to the central longitudinal axis (4), so that in a mounted state a force component (K) is exerted unto the clamping webs in a radial direction.
